There's no shortage of innovation in the security-technology industry, giving business owners more high-tech cameras, locks, systems and software to pick from every year.

Companies ranging from large, established manufacturers to high-flying startups are developing next-generation biometrics tools and smartphone-based entry systems that may provide businesses with a security advantage.

While advances in technology are exciting, companies should still be cautious about making investments in the newest products, experts advise. Sometimes, it's best to let another company's facilities be the proving ground for cutting-edge technology, said Jim Francis, senior vice president of security consulting services for New York-based T&M Protection Resources.

“One client that I have gave me the best advice: Be the first to be second," he said.

For those on the lookout for the next big thing in security technology, here are are trends consultants are seeing in the market.

Biometrics

Biometrics technology, which verifies identity by scanning a person's fingerprint or other features, is advancing quickly.

For instance, some biometrics tools now scan the eye's iris, rather than its retina, said Gary Elert, president and founder of technology and security consulting firm Elert & Associates, based in Stillwater, Minn. Iris scanning with infrared light is faster — it can take less than a second — and works through contacts, glasses and even some sunglasses.

“Infrared light is generally not harmful to the human eye and is more publicly acceptable than a laser,” Elert said.

Companies also are aiming to address a biometrics-technology shortcoming often highlighted in movies when a criminal uses a dead victim's hand to open a door.

spend lots of money promoting themselves on social media, so free mentions by employees on Facebook, Twitter and other networks are a good thing, right? Maybe not. Such postings, even when well-intentioned, can pose security and other risks for your firm. Here are some things that can go wrong, and some tips on setting your policy.

Many businesses grant subcontractors client access into their systems for all types of reasons, from file sharing to accounts payable functions. If systems aren't locked down, a small company can be opening itself to major security concerns.

For more effective data security, experts often recommend the implementation of a security policy so employees, clients and subcontractors can understand their roles and responsibilities. Unfortunately, the reality is that a security policy tends to be one more boilerplate document that doesn't get read, much less followed.
